How many can eggs broody hen sit on?

The number of eggs a broody hen can sit on depends on her size and breed. Generally, a small hen can sit on 8-10 eggs, while a large hen can sit on 12-15 eggs. Some hens have been known to sit on as many as 20 eggs, but this is not recommended as it can be too many for the hen to properly cover and keep warm. If you are unsure how many eggs your hen can sit on, start with a small number and add more if she seems comfortable.
